CARBURETER.

SPECIFICATION forming part of Letters Patent No. 223,490, dated January 13, 1880.

Application filed November 17, 1879.

To all whom itmay concern Be it known that I, HENRY C. DE WIT'r, of Chicago, in the county of Cook and State of Illinois, have invented certain Improvements in Oarbureters, of which the following is a specification.

The object of this invention is to provide a cheap and simple apparatus for carbureting gas or air, which shall expose, in proportion to the space occupied, a large carbureting-surface; and to this end the invention consists in the peculiar construction and arrangement hereinafter described, the leading feature consisting in shallow oil receiving and holding trays provided with upright skeleton-frames, from which are suspended strips of wicking or like fibrous material, separated by intermediate rolls of cotton batting covered with excelsior.

Figure 1 represents a vertical central crosssection of the apparatus; Fig. 2, a perspective view of one of the trays removed from the body; Fig. 3, a perspective view of one of the rolls of cotton.

In constructing the apparatus I first provide a closed body, A, having inlet and outlet pipes at b, an oil-supply pipe, 0, and inside shoulders or projections, d, to sustain the bottom tray. I next provide two or more trays, B, each of proper size to fit within the body, as shown. Each tray is made in a shallow form, with an upturned edge and small overflow-pipes e, to maintain the oil at a fixed depth therein and permit any excess to flow down into the tray beneath. Each tray is also provided with rigid upright arms f, sustaining at their upper ends a horizontal wire frame,v g, formed by crossing and fastening together a series of wires in such manner as to form a number of small squares. Over the wires I fold and secure strips, G, of wicking or like fibrous material, which are permitted to hang down and rest at their lower ends inthe tray, as shown in Figs. 1 and 2.

It will be noticed that the arrangement of the strips, which will be appliedto the entire frame, is such that small square spaces or pockets exist between them. Into each of these pockets 1 insert an upright roll of cotton wadding or batting, such as is commonly .s ldi the marke ,.W st me a moderately close manner, and securing the edge, so that it may notunwind. The wadding rests in the tray and extends upward nearly to the level of the frame g, and before or after being inserted each roll is covered around the sides and top with the fine threadlike wooden shavings known in the market as excelsior, and indicated in the drawings by F. The excelsior is packed in place quite closely, and, in connection with the cotton and wicking, forms a large absorbent mass,

filling the tray and extending upward to the frame Gr.

After the frames and trays are ready, they are inserted into the body, one upon another, and the body closed, the bottom tray being supported by the shoulders in the body, and the others supported by resting upon each other.

Oil being supplied through the pipe saturates the absorbent material in the top tray,

fills the tray to the top of the overflow-pipes, and continues downward in like manner into and through the tray or trays below.

The gas or air entering at the bottom passes through the overflow and worksits way through the mass of saturated material, and finally escapes at the top, after having been compelled to pass over a very large surface, and thoroughly charged with the hydrocarbon.

In order to prevent the passage of air around the edges of the trays, the space between them and the body may be filled with excelsior or other packing.

The office of the cotton and the wicking is to carry the oil upward freely and rapidly and keep the excelsior saturated, and the latter is designed to expose the greater portion of the surface to the air or gas.

I am aware that wicking, sponge, and other similar absorbent substances have been used in carbureters in connection with trays and elevated sustaining devices; but I am not aware that said elements have been before constructed and arranged in themanner shown in the drawings.

The excelsior forms a light loose mass, through which the air can readily pass, and which exposes a very large surface of the oil, while the cotton and wicking serve to deliver the il theexc siqrand keep fi ee119 99 thoroughly saturated than would otherwise be seated in the cells, and the eXcelsior, also seated the case. in the cells around the cotton, as described 10 Having described my invention, what I and shown.

claim is 5 The combination of the oil tray or receiver,

the elevated lenticular frame, the series of Witnesses:

wicks suspended from the frame and forming P. '1. DODGE, the series of small pockets or cells, the cotton WILLIAM W. DODGE.
